Having escaped the initial pursuit, your group of six (Noah, Lanz, Eunie, Mio, Sena, and Taion) must now navigate the perilous landscapes of Aionios while being hunted by both nations.

• Journey: Traverse the Forerunners' Tower and the Erythia Sea. Be mindful of stronger enemies in these areas. It's a good time to experiment with different class combinations and master your Arts.

• Story Progression: Within the City, you'll learn more about the true nature of the world and the entity known as Z. You'll also meet key figures who will aid your cause.
• Boss Battle: A confrontation with Moebius K will occur as you attempt to leave the City.
  • Strategy: Moebius K is a formidable foe with powerful area-of-effect attacks. Ensure your healers are actively managing the party's HP. use Chain Attacks strategically to deal burst damage and recover HP/TP. Consider equipping accessories that boost defense or HP for this fight.
